3 views (last 30 days)
eqn1=F*125.9-G*355.4==12;
eqn2=-F*251.8-G*125.9==16;
eqn3=F*125.9+G*355.4==13;
i want to find out values of F and G from above equations. Is there any commands in matlab for solving this equations?. Help me to solve this in matlab?

Of course you won't get a solution that exactly solves all three equations.
But you will get a "best" solution in the least-squares sense if you set
A=[125.9 -355.4;-251.8 -125.9; 125.9 355.4];
b=[12; 16; 13];
[F; G]=A\b;
Best wishes
Torsten.
